5 DIY decorating projects – Easy DIY upgrade: Prepare walls for kids' art. You long to be that cool mom who's laid-back enough to let the kids freely decorate their rooms, but you imagine a wall Swiss-cheesed with nail holes and hanging hooks. Now you can give them free rein over their decor by covering a wall with magnetic primer, which contains nontoxic iron particles. You'll need at least two base coats under the paint of your choice. The resulting surface will hold magnets, which in turn can hold artwork, Derek Jeter posters, and that Got Milk? ad collection.

5 DIY decorating projects – Easy DIY upgrade: Hand towels in a window box. You worked for hours helping mom plant pachysandra way back when, but that doesn't help you now, as you try to nurture a briefly blooming geranium display in an outdoor window box. It's time to throw in the towel―literally. A standard window box installed inside just below the sill proves fertile ground for storing a colorful array of hand towels and washcloths. Stick to one shade or mix it up and you'll have your own version of a window garden. Even mom may reap the benefits.

5 DIY decorating projects – Easy DIY upgrade: Give your sofa a new look. Your favorite sofa is having a midlife crisis: It's not worth reupholstering, but it's not ready for the junkyard, either. A pre-made slipcover is just the thing to see it through. For a tight fit, use a wooden spoon or a spatula to work the fabric deep into the couch's crevices. If the arms of a chair or sofa are too narrow, beef them up with foam quilting or comforter batting (available at most fabric stores). To keep a slipcover from sliding out of place on a leather couch, lay nonslip carpet padding on the seat cushions.

5 DIY decorating projects – Easy DIY upgrade: Frame fabric for quick, inexpensive art. You'll need a staple gun, a stretched canvas (sold in art-supply stores), and some fabric, preferably heavy linen or cotton in a pattern without straight lines. Cut out a piece of the fabric that is four to six inches longer and wider than the frame. Place the material pattern-side down on your work surface, and center the canvas facedown on top of it. Then staple the cloth to the back of the frame

Start simple: Hanging artwork lower on the wall will improve any room

Turn it down -- bright light is the enemy

Want to elevate your home without taking on a complete overhaul? Interior decorator Nick Olsen -- DIY whisperer and master of the cheap trick -- reveals the little tweaks that make the biggest impact.

Real Simple: How did you get started in this field?

Nick Olsen: Right after getting my architecture degree, I read about the designer Miles Redd in a magazine. I was so blown away by his bold aesthetic and everything he'd accomplished by the age of 35 that I wrote him a letter asking for a meeting. Two weeks later, I had my first full-time job, as his assistant. It was fate!

Olsen: Lower the artwork. People tend to hang it too high; it should be at eye level. And don't worry about having something on each wall. It's better to cluster art in one or two spots than to spread it out.

Real Simple: Decorating a huge room can be intimidating. How do you deal with soaring spaces?

Olsen: My philosophy is to fill them with large-scale furniture and art. If you're a less-is-more type, go for one massive piece, like an amazing painting over the sofa.

Real Simple: Suppose you can't afford art that big?

Olsen: Buy a blank canvas and paint it yourself. Pick the most interesting color in the room (as long as it's not already the dominant color) and just cover the canvas in that shade, using the same paint you'd use for walls. There's no way to mess this up, and it costs next to nothing. Google [famed abstract artist] Ellsworth Kelly for inspiration. He has pieces like this hanging in the Whitney Museum.

Olsen: Nearly every room has a door. Work it. Paint it a glossy black: It takes only two hours and gives a room instant sass but won't eat up any valuable real estate.

Real Simple: Say you can revamp only one room. How do you keep the rest of the place from looking shabby?

Olsen: Fiercely edit the undone rooms. Get rid of the junk; keep only essentials. You'll be poised to redecorate when the time comes—and until then your rooms will feel calmer. Tell visitors you're experimenting with minimalism.

Real Simple: What do you always want to fix when you go into someone's living room?

Olsen: The floor plan and lighting!

Real Simple: Break that down for us.

Olsen: A good living room needs a comfortable place to sit, a place to rest your drink, and a place to read a book. But people default to the school-dance arrangement, where everything is pushed back against the walls. So I start by moving the furniture closer together, toward the center of the room. Then I fill out the arrangement with occasional chairs and tables to create functional seating areas. It makes the space feel so much more intimate and conversational.

Olsen: A common feature of boring rooms is a lack of color. Start there, and think from the ground up. Buy a patterned rug you love: here's your palette. Go for a geometric dhurrie if you like modern, or multicolored stripes if you're more traditional. You can pull the wall and furniture colors from the rug, then pick up its accent tones in pillows and other accessories.

Real Simple: Speaking of color, are there any surprising shades you're really into right now?

Olsen: I think fuchsia should be the color of the year. It's so rich and chic, it's like red's hipper sister. I'd use Benjamin Moore's Gypsy Pink on walls in a room with neutral furniture and gray trim. Or just do the ceiling (use high-gloss for that).

Real Simple: One piece of advice you'd shout from the rooftops?

Olsen: Stop overthinking every little change and just try it! It's easy to say, "Oh, that desk will never work next to my bed." Move it and see how it looks. Sometimes pulling that blue armchair from the den into your green living room can work miracles.
